i dont know why u feel that way? i see your point if you were doing some 30psi 600hp setup, but the RBs are only going to give about 50hp over stock setup. So your looking at roughly 320-340 range? Dont get me wrong you can modify and tune for other Hp goals but even then i have yet to see any 335's with 500hp/600hp (maybe 2 or3). So just think about the situation. Ive already purchased them i never ragg my car so im not worried one bit i cant wait..and they're close to being undetectable/warranty......
